Heat Fatigue-Exhaustion-Stroke

Heat also has the potential to be of great danger to the outdoor athlete, especially during the summer. Side effects range from sluggishness and fatigue to dehydration and potentially fatal heat
stroke. Fortunately for us athletes, heat-related illnesses are fairly easy to prevent and treat.

Heat Fatigue

One such heat-related illness is heat fatigue. It's generally caused by fluid loss and
responds well to rehydration and rest. Because an inadequate diet or caloric intake is common with the summer athlete, it too should be evaluated when sluggishness and fatigue are experienced. Like
heat-related fatigue, heat cramps are also a result of insufficient fluid intake. These painful muscle spasms generally occur in hot and/or humid environments when the athlete overexerts him or
herself.

Heat Exhaustion

Heat exhaustion is another common heat-related illness experienced by athletes in the
summer. Simply speaking, you're working the body so hard it's just too damn hot to carry on! Technically speaking, it's a group of symptoms that occur when your body's rate of heat production is
greater than it's rate of heat dissipation. Symptoms generally begin to occur when the body's core temperature rises above 102-F. The onset is sudden with the athlete becoming clumsy as well as
confused. Additional symptoms include headache, dizziness, chills, nausea, vomiting and weakness. Signs of heat exhaustion are an ash-gray color of the skin, lowered blood pressure, and a rapid
pulse. Immediate rehydration, body cooling, and rest is crucial.

Heat Stroke

Heat stroke can result when the body's temperature rises above 105-F, resulting in extensive
tissue damage to the body. Often, the onset of heat stroke can be abrupt with the athlete experiencing a severely altered mental status or possibly a sudden loss of consciousness. Death can occur
rapidly unless rapid cooling and rehydration is immediately performed. Full body immersion in cool water with simultaneous rehydration with cool fluids is most effective.
